4 Claims.

The subject matter of this application is divided out of my applicationSerial No. 724,114, Means for use in spinning and in liquid-treatingtubular rayon packages (Patent No. 2,065,526).

In an application, Serial No. 724,113, Patent No. 2,089,962, I haveshown, described, and claimed improved apparatus for treating finefilamentous thread; as also, described and claimed improved processesfor treating such thread. A part of the apparatus set forth in saidapplication, Serial No. 724,113, is improved supports for use inliquidtreating such thread in tubular package form, and improvedsupport-attachments for the wound-bobbin-supporting-and-rotatingspindles of package-spinning machines. Certain forms of package-supportsand attachments shown and described in said application, Serial No.724,113, are some of those shown, described, and claimed in the instantapplication.

The invention claimed in said application, Serial No. 724,113, relatesto improved methods and apparatusfor liquid-treating rayon in packageform, such as cakes, wound spools or bobbins, etc., after the rayonthread has been collected in such form by spinning machines from theprecipitating bath in which the rayon filaments are set up. The rayonthread as so collected is comprised of a comparatively large number offilaments which are twisted as some forms of packages are beingcollected, and are collected untwisted in other forms of packages.

The treatments to which the rayon package is subjected by the improvedprocess and apparatusclaimed in said application, Serial No. 724,113,are the different treatments to which the rayon is necessarilysubjected, before the precipitated and package-collected thread can beconsidered a final product ready for the market, such as various waterwashings, desulphurizing, bleaching, oiling, sizing, dyeing, drying, andother purifying and finishing operations.

Primarily, the process of said application, Serial No. 724,113, consistsin loosening up the package, when purifying the same in its initialcollected form, so as to provide for all parts of the package theirrespective natural scopes of free play, relative to other parts of thepackage, thus effecting a natural alteration of the relative positionsof all parts of the thread comprising the 50 package and ofthe differentportions of the package. This is done without injuriously disarrangingthe thread or the filaments thereof, so that the package may be dried inthe treated package form, preliminary to the sale thereof for the mar-55 ket, or to the rewinding thereof into some other form of package forsuch sale, without inducing strains or an immobile condition in anyportion of the package which would result in a nonuniform dyeing orbarred efiect. Thepurification and other treatments of the package arecarried out without unduly impairing the tenacity and elasticity of thethread required for later handling and processing or for use, andwithout setting up local tension areas or non-uniform strains.Essentially, the process consists in pulsating the package body by meansof the treating liquid on the openings of improved forms of skeletoninserts and bobbins upon which the package is mounted and while spacedportions of the latter are free to move to a predetermined extent,through said insert openings, under the pressure of the treating liquid.

Some of the forms of the bobbins, above-mentioned, upon and through theopenings of which the pulsating package body is free to move, and someof the forms of the improved bobbin-attachments, form the subject matterclaimed in the instant application.

In said application, Serial No. 724,113, there is a disclosure ofprocesses of, and means for, causing the treating liquid alternately toflow in opposite directions though tubular rayon packages, viz., fromthe outer face to the inner face, and from the inner face to the outerface. When the treating liquid passes from without the tubular rayonpackage through the body thereof and into the interior of the package,the package is deformed by reason of parts thereof moving inwardlythrough the openings of. the insert or.

bobbin upon which the package is mounted. This inward movement is underthe pressure of the treating liquid and is preferably permitted up to apredetermined maximum extent, and loosens up the package to a degree andpermits a natural altering of the relative positions of the parts of thethread comprising the package and of different portions of the package.

Said other application, Serial No. 724,113, also explains how rayonpackages of the character therein shown are spun so that the strands ofthe outer face, of the package prevent any material enlargement of thepackage perimeter. Therefore, the pressure of the treating liquid fromwithin the package outwardly, i. e., when the flow of treating liquid istoward the outer face of the package, does not bulge or deform thepackage outwardly so as to increase its perimeter, under any pressuresthat are practically usable for such treatments. However, those portionsof the package which are not moved inwardly by liquid passed inwardly ofthe package body are djusted somewhat outwardly during such treatment,as clearly shown in the accompanying drawing and as will hereinafter befully described. .Explanation is also made of the fact that at somestages of the process complete passage of the treating liquid throughthe package.-

would not be effected, but only a tendency to pass through the packagein the direction of liquid flow; also,- that after the package had oncebeen inwardly deformed, it would reestablish itself in its originalform, or tend to so reestablish itself, when the direction of liquidflow is again outwardly of package.

Said other application, Serial No.' 724,113, makes a disclosure ofcertain methods and means for assembling a plurality of packages in aseries of vertically-aligned tiers in a treatment casing within whichthe packages are subjected to the action of the treating liquid. Meansare disclosed for recirculating the treating liquid through thetreatment casing and the packages mounted therein, and for automaticallyand adjustably periodically reversing the direction of liquid flow.

Said other application, Serial No. 724,113, illustrates the use andapplication of the improved process and apparatus therein disclosed, byreference to a water-washing of rayon cakes and wound rayon bobbins. Itis also disclosed in said other application that packages of the woundbobbin or spool shape are collected from the spinning machinesupon'perforated bobbins or supports and that it is the purpose of theinvention disclosed in said application to liquid-treat the woundbobbins in situ upon the same perforated bobbins. However, inasmuch asthe liquid treatment pulsates the packages upon openings in the bobbins,which openings would render diflicult, if not impossible, the spinningof the wound bobbin in perfect cylindrical formation, removable bobbinattachments are provided 'for covering these openings during thespinning operation.

Some forms of the removable bobbin attachments above-mentioned form partof the subject matter claimed in the instant application, being termedmeans for use in spinning annular rayon -packages and forliquid-treating the collected packages in situ. The claims of theinstant application are directedv to means for use in spinning and inliquid-treating annular rayon packages,'wherein no limitations areincluded relating to stop members for limiting the movements of spacedportions of the package through the openings of the skeleton bobbins;whereas, the claims of the parent application, Serial No. 724,114, fromwhichthe-subject matter of the instant application has been divided out,are directed to forms of skeleton inserts and bobbins having such stopmeans.

The annexed drawing and the following description set forth in detailcertain means illustrating my improvedrayon-package supports andimproved support-attachments, such means disclosing, however, only a fewof the various forms in which the principle of the improved supports andattachments may be embodied.

In said annexed drawing:

Figure 1 is a fragmentary vertical section of a fragmentary portion of atreatment casing in which a plurality of rayon packages of the woundbobbin or spool type are mounted for liquid treatment, the packagesbeing mounted upon special skeleton bobbin supports.

Figure 2 is a plan section, taken on the plane indicated by the line2-2, Figures 1 and 3, the

shape in which the wound bobbin is spun, or, if it has been deformedinwardly by previous liquid treatment, in which it tends to reestablishitself, when the flow of treating liquid is from within outwardly, beingshown in full lines, and the shape assumed by the wound bobbin package,or which it tends to assume, when the flow of treating liquid is fromwithout inwardly, being suggested by dot-and-dash lines;

Figure 3 is a vertical axial section, taken in the plane indicated bythe line 33, Figure 2;

Figure 4 is a fragmentary axial section, taken in the plane indicated bythe line 4-4, Figure 2;

Figure 5 is a fragmentary axial section of thewound-bobbin-supporting-and-rotating portion of a spindle of a spinningmachine provided with a perforated bobbin support and a supportattachment, both of which embody my improvements, the attachment servingto hold the thread circular as it is being collected from theprecipitating bath and thus insure cylindrical inner and outer surfacesfor the wound collected bobbin. Thus, a regularly annular wound bobbinpackage is gathered even if the wound bobbin being gathered is supportedonly at spaced points by the support or, in other words, is beinggathered on for liquid treatment.

Referring particularly to Figures 1, 2, 3 and 4, there is therein showna form of support I0 for rayon packages of the wound spool or bobbintype. A fragmentary portion of a vertical tier of such wound bobbinpackages I is shown in Figure I mounted for liquid treatment, thevertically adjacent wound bobbins I being spaced apart by upper andlower laterally-extended flanges I4I of annular spacers I40. Therespective wound bobbins 1 are spaced apart a distance equal to thecombined depth of the flange portions of a. spacer I40, and the bodyportions of the spacers I40 are spaced apart by the bobbin supports I0.These supports I0 each comprise a pair of end rings I42 connected by aplurality of and faces 1' of the wound bobbin 1, and thus cause the endfaces I of the wound bobbin I and the adjacent faces of the flanges I4Iclosely to contact one with the other throughout the entire distancewherein they are in vertical alignment. When the wound rayon bobbin 1 ismounted upon the support I0 and is subjected to the action of a treatingliquid applied to the outer surface of the wound bobbin 1, spaced woundbobbin portions pass through the openings of the bobbin I0 between therespectively adjacent bars I43 and assume the positions clearlyindicated by dotand-dash lines in Figure 2, or tend to assume thesepositions, the inner face and the outer face of the wound bobbin 1,under these conditions,

being'indicated by the respective numbers I" and I46, both being ofirregular or wavy outline.

Referring particularly to type of bobbin such as shown in Figure 1 isprovided, but these Figures 5 and 6 also disclose a bobbin attachmentapplied to the wound-bobbincollecting spindle of a spinning machine,whereby the wound bobbin can be collected with substantially cylindricalinner and outer faces although it is being collected on a bobbin orsupport which is provided with windows or openings large enough topermit the inward and outward pulsation of the wound bobbin packagethrough such openings when the package is being processed by a treatingliquid applied thereto alternately in opposite directions. In otherwords, the wound bobbin package 1 is gathered upon the same support orbobbin as is used for the liquid-treating operations applied to thewound bobbin subsequent to the collecting or spinning of the woundbobbin, even though this support is provided with the comparativelylarge openings or windows.

The bobbin attachment above-mentioned is formed with a hub member I41secured to the bobbin-rotating spindle I48 of a spinning machineby'means of a set screw I49. Formed upon .the outer surfaceof the hubmember I41 are a plurality of transversely spaced ears I5I to which arepivotally secured by means of pins I52 a plurality of spacedlongitudinal arms I53 having hub portions I54 mounted on the pins I52,which hub portions I54 are formed with heels I54 closely'contacting theouter surface of the hub member I41. Each of the arms I53 is formed witha plate I55 having an arcuate exterior surface of a width slightly lessthan the are between the exterior collecting surfaces of contiguousbobbin bars I43, each plate I55 lying between two adjacent bars andhaving its outer surface lying in the circle defined by the exteriorcollecting surfaces of the bobbin bars I43. These plates I55 have endextensions I56 adapted to contact at their outer side surfaces with theinner surface of one of the bobbin end rings I42. When the wound bobbinpackage 1 is being gathered or collected by'the spinning machine, theplates I55 form wound-bobbin-supporting members between the respectivelyadjacent bars I43 of the bobbin I 0' and their exterior collectingsurfaces form with the exterior collecting surfaces of the bars I43 asubstantially continuous cylindrical collecting surface so that thebobbin package can be efiectively and properly collected and wound. Allparts of the bobbin attachment capable of contaminating the wound bobbinpackage are made of hard rubber, or Bakelite, or other non-. corrisivematerial, or may be covered with noncorrosive material.

Extended inwardly from the center of the wound-bobbin-supportingplates-l55are radial webs I51 having inner end clamping pad portions 158of arcuate formation. These pad portions I58 are adapted to contact theouter cylindrical surface of a spreading head I60 having an extendedconical portion I60 and formed upon a rod I59 having a handle I62 at oneend and a pin extension I61 at the other end adapted to engage a recessI in the hub member I41. Outward movement of the rod I59 is limited byan enlarged shoulder portion I14 thereof which is adapted to contact theinner ends of the pads I58. When there is no bobbin on the spinningmachine, and therefore the attachment is not sup- Figures '5 and 6, a-

ported, the arms I53 are collapsed by a rubber band I13 seated in agroove formedin the exterior face of the plates I55, which ban'd I13prevents the lowermost arms I53 from falling outwardly. The arms I53 areprevented from falling inwardly by'reasorr of the-contact of the heelmembers I54 with the outer surface of the hub member I41.

When it is desired to spin a rayon bobbin 1 upon a bobbinor suport I0and upon the spindle of a spinning machine having my improvedattachment, the bobbin I0 is applied to the attachment, which is fixedto the spinning machine spindle, in the following manner. The bobbin I0ispassed over the arms I53 of the attachment with the bars I43 of thebobbin passing between the adjacent edges of adjacentwound-bobbinsupporting plates I55, as shown in Figure 6, and the endextensions I56 of the plates I passing through one end ring I42 of thebobbin I0, as shown in Figure 5. Meanwhile, the inner extension I6I ofthe rod I59 has been positioned in its innermost position in the recessI50 of the hub member I41. This rod I59 is then pulled outwardly bymeans of the handle member I62, the conical head portion I facilitatingthe entrance of the head I60 within the circle defined by the clampingplates I58, the outward movement of the rod I59 being continued untilthe shoulder I14 engages the inner ends of the clamping plates I58, asclearlyshown in Figure 5. Thus the pads 158 are tightened so as toposition the wound-bobbin-supporting plates I55 substantially in thecircle defined by the rubber sheaths I44 of the bobbin bars I43, whichis the circle that it is desired to define by the inner face of thewound bobbin 1 when it is gathered or spun.

Important advantages attach to the spinning of the rayon packages ofbobbin formation upon bobbins which are of such constructions that theycan also be used as supports, after spinning, for the necessarypurification and other processing. It is necessary with previous typesof bobbins to unwind the rayon package from the bobbin and rewind intoother package forms, after washing, and before subsequent processing,and in so doing, the rayon fibres are damaged, and other injuriousresults occasioned. If the rayon package upon the previous types ofbobbin is'not so re wound, the benefits of the inward shrinkage of thepackage obtained by the improved process of my application Serial No.724,113, cannot be realized. My improved attachments for thewoundbobbin-supporting shafts of spinning machines permit propercollection of the rayon bobbins upon perforated bobbins which then serveas suitable supports upon which the wound rayon bobbins remain mountedfor subsequent processing.

As will be clearly seen in Figure 6, the plates I55 do not fill theentire collecting surface portions between the adjacent bars I43, but docomplete the collecting surface to an extent sufficient to make acontinuous collecting surface fro-m a practicable standpoint. In otherwords, the comparatively slight spaces between the edges of the platesI55 and the adjacent bars I43 are'not large enough to prevent thecollection of the wound bobbin with substantially cylindrical inner andouter faces.

My improved forms of bobbins are also adaptable to the well-knowndrip-washing of rayon packages. The wound bobbins mounted on the bobbinsmay or may not be rotated while water is permitted to drip over thewound bobbins. Preferably, the bobbins are supported between spacers"pairs of which the bobbin 'tially continuous, and means for held inposition similar to the stacking arrangement of the wound bobbins andbobbins, shown in Figure 1. Furthermore, in lieu of the drip method, thetreating liquid can be applied to the rayon packages mounted on myimproved bobbins and stacked as shown in Figure 1, through a perforatedtubular pipe located within the stack, the liquid being applied withoutpressure, thus loosening up the package and inducing inner movementthereof.

When spinning wound bobbin packages, the thread is gathered untwisted,and therefore it.-is necessary subsequently to twist the thread on-aseparate machine known as a twister or a spinner. I wish to point outthat the elongated windows of my improved forms of bobbin do not offerresistance to free twisting, since the bobbin with the wound rayonbobbin mounted on it is revolved at a high speed during the twistingoperation causing the cross-sectional shape of the wound bobbin packageto take a form similar to that which it assumes, or tends to assume,when it is subjected by my improved process to the action of a treatingliquid moving from within the package outwardly. Since the rayon threadis dry when being twisted, no unequal strains such as my improved bobbinsupports seek to eliminate are set up by the centrifugal action.
